    minimus2 woes

    I'm trying to merge an alignment to a reference sequence and a de novo assembly using the same Illumina reads. It seems like minimus2 would be the right tool for the job, but every time I run it I get no overlaps and all the sequences just dump into singletons.seq. Just as a test, I tried assembling the alignment contigs to themselves (i.e. made a file with two copies of the alignment contigs, then performed alignment with minimus2) and again got no overlaps and all singletons!

    I'm already a little wary of this program since I had to go in and modify it for myself just to get it to run (I kept getting usage errors on dumpreads steps 12 and 13 until I moved $(BANK) after the -m/M options instead of before), but that's the only change I made. Is there some other glitch I don't know about?

    Any suggestions?

    Full disclosure: I didn't install qt3 when I installed amos since it wouldn't compile on OSX 10.6, but my impression is that's just for the viewers and minimus shouldn't depend on it.

    Thanks.

    Never mind. I fixed it. It seems that at the ovl2OVL step (step 23), the output AMOS ovl file was empty. When I changed the extension of the AMOS ovl output file in minimus2 from .OVL to .ovl2, the output was no longer empty and the program (finally) worked like a charm. Maybe it's a Mac thing. I don't know, I'm just glad it's working. Sorry for for clogging up the forum here, but maybe my trial and error process can save somebody else some time and aggravation someday...

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

        New Genomics Technologies Take Aim at Long-Standing Limits
        by SEQadmin2


        Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

        We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
